Technical Specifications:

With over 450 active nuclear reactors in the world today, it’s prudent to take precautions in case of disaster. 

Featuring cutting-edge engineering and design, the CM-6M gas mask is crafted from bromobutyl rubber with a hypoallergenic inner masks for superior comfort and function. Dual-layer construction helps prevent fogging and makes breathing easy. Equipped with a speech diaphragm ensuring 95% intelligibility of speech, you can communicate with members of your party through the mask.

The included potassium iodide tablets help prevent thyroid damage from fallout and excess radiation, which dissipates up to 200 miles downwind from a nuclear catastrophe. It is advised you take the tablets before or soon after exposure to excessive radiation levels.

The included ThyroSafe™ tablets are the only FDA-approved tablets available in the US—ideal for adults, with a cross-score to provide reduced dosing for children. A single dose of potassium iodide protects the thyroid for about 24 hours—any radioactive iodine taken into the body after dosing is rapidly flushed out. 

The MIRA Safety drop-leg pouch holds the entire kit while mounted out of the way on your leg. Featuring rugged construction designed to withstand abuse without tearing, the pouch comes with a flexible mounting system and padded back for comfort.  

NOTE: The CM-6 mask is one size only. While the 5-point harness provides a flexible fit, the user’s face must be free of facial hair with no obstructions in the way of the sealing gasket. The mask enables the use of a glasses insert (sold separately), which insert into the mask’s rubber slip.

Filters can be fitted to the left or right inhalation chamber. The unused chamber must be sealed with a filter plug. Ensure the filter plug is tightened and screwed into place. Each inhalation chamber is fitted with EN 148-1 standard 40 mmx1/7” thread. Ensure your filters are compatible. 

The effectiveness of the filter depends on the toxins in your environment. The included NBC-77 SOF filter is designed for use in environments with at least 19.5% oxygen (lower oxygen levels will necessitate a SCBA). The filter is designed to offer protection from radioactive particles, viruses, bacteria, gases, vapors and a range of noxious fumes.

  • CM-6M or CM-7M gas mask
  • (20) potassium iodide tablets (65mg)

Ask a Question
  • My face dimension is quite small (Forehead 5.90”, Length 7.08” and Chin 4.72”). Will CM-6M fit for me?

    The CM-6M fits 95% of the population. I would suggest ordering and trying one on. If it doesn't fit, we can swap it out with a CM-7M in a smaller size.

  • I wear prescription eyeglasses, do I have to get a different mask lens or can the mask be worn with my eyeglasses?

    The CM-6M mask is compatible with the 3M Safety 6878 spectacle kit. At this time, we do not have a spectacle kit available for the CM-7M, and we are unsure of which kit fits with the mask. I would suggest reaching out to Safe Vision, a 3rd party provider, as they have many kits available.

The Mask

I ordered in February on the upswing of the increased demand for these. It showed up a little before they promised and everything about it so far has been top notch. It fits perfectly in the canteen system works great.

CM-6M Package, didn't have all items

As a US Marine who has had a lot of training with other masks including the current M50, the quality of the product is amazing and is up to par with what they advertise. I'm very happy with what items I did actually receive. I purchased two kits, and only received the mask, and filters which are the most important, but after two months I still haven't received the canteens or carrying cases. Hopefully they come soon. I was able to get responses on why they were missing, but they referred to me as a different person, not a big deal. It would have been nice to have a letter in the box saying the other items would come later instead of me freaking as to why it's not there.

Great quality and customer service!

Items seem to be of an excellent quality, but only half my order came initially. However, the customer service department sent the reminder of my order within days of calling them directly.

The most comfortable easy sealing gas mask I have ever put on!

After much research I ordered a Mira CM-6M for myself and wife. I have a military background and wanted something reliable from a reputable company. This led me to nrrow my search to 3 possibilities based on value, reviews, and features I went with Mira...hands down the easiest sealing most comfortable gas mask I ever put on. I hope I never need to use it but I have confidence that if I do it will be ready to go and be pretty darn comfortable too.
